The objectof our invention is. to provide a condenserapplicable for use in steam cooling systems for internal combustion engines, said condenser comprising juxtaposed direct and reflux condensing units of novel construction Thecondenser herein shown comprises jux v taposed direct and reflux condensing units having separate upperchambers and sep- ILZO arate lower chambers, the lower chambers being connected by a passage which is preferably valved; j

The direct condensing unit of the condenser is herein shown as comprising passages 1 connectingupper and lower chambers 2'and 3,

theupper chamber 2having a steam inlet port 4.

he reflux "condensing unit of the condenser, is, located immediately in front of the d1- rct condensingunit and it is herein shown as comprising passages 5 connecting upper and lower chambers6 and 7, the upper chamber fihaving a removable fillingcap 8 and also a vent 9 to external atmosphere. The lower e chamber? is provided with a discharge port 10 for the wfater of condensation. Aiwater overflow passage 11 may be provided for the chamber. 7 so that a specified quantity of water may be supplied to the system when 9 desired, the chamber endof which passage is normally water sealed so that the steam will be caused topass upwardly through the re flux condensing unit rather than permitted to escape through the said overflow passage.

A passage leads from the lower chamber 30]. the direct condensing unit to the lower chamber 7 of the reflux condensing unit. In the presentiinstance this passage is shown as valved andas constructed as follows .50 A hollow .plug has its closed lower end 13 1926. Serial No. 101,724.

moron I'YNE, or

screwed into the bottom of the hollow casing which enclosesthe two lower chambers 3 and 7. A valve cage 1 1 is screwed into the open upper end of the said hollow plug, which cage has a port 15 normally closed by a ball valve 16. Theside wall of the hollow plug has a port 17 opening to the lower chamber 3 of the direct condensing unit. From the above description it will be seen that the plug and valve may be readily removed, when so desired.

A drain cook 18 may be provided for the lower chamber 3 of the direct condensing unit and a drain passage 19 and cock 20 may be provided for the lower chamber 7 of the refluxcondensingunit and the valve cage 14.

In the present instance a single hollow casing 21 is provided with a partition 22 to form the upper chambers 2 and 6 of the direct and reflux condensing units, and a single L-shaped hollow casing 23 is provided with a partition 24 to form the twochambers 3 and 7 of the direct and reflux condensing units.

In operation :The steam entering the upper chamber 2 of the direct condensing unit is more orless condensed in the passages 1, the water of condensation gathering in the lower chamber 3. The water of condensation passes upwardly from the lower chamber 3 into the lower chamber 7 of the reflux condensing unit where it may be drawn ofl through the passage 10. If more steam is being generated than can be condensed in the direct condensing unit, it will pass upwardly from y the chamber 3 into the chamber 7 through the water therein which will assist in the condensation of the steam) and from thence upward ly through the passages 5 into the upper chamber 6 where such steam as has not been condensed in the reflux condensing unit will escape to external atmosphere through the vent 9. It will be understod that this reflux any well known or approved form.-

' flux condensing unit.

Where a specified quantity of water is reguired to be supplied to the system, the overow passage 11 is provided, the end of which assage which is located in the chamber eing arranged to be normally sealed by the water in said chamber so that the steam will be caused to pass upwardly through the re- VVith other systems, the overflow passage may be omitted, the vent 9 being suflicient for the outward passage of the air during the heating period and for its return during the cooling period.

While describing this condenser as adapted to receive water it is to be understood that any suitable liquid may be utilized.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of our invention; hence, we do not intend to be limited to the particular embodiment herein shown and described, but

What we claim is:

1. An air cooled steam condenser comprising a direct condensing unit having connected upper and lower chambers and a reflux condensing unit having connected upper and lower chambers, the reflux condensing unit being located in proximity to the direct condensmg'unitgthe upper chamber of the direct condensing unit having a steam inlet port and the lower chamber of the reflux condensing unit having a water discharge port and a restricted passage for the escape of the water of condensation from the lower chamber of the direct condensing unit into the lower chamber of the reflux condensing unit.

2. An air cooled steam condenser comprising a direct condensing unit having con nected upper and lower chambers and a reflux condensing unit having connected upper and lower chambers, the reflux condensing unit being located in proximity to the direct condensing unit, the upper chamber of the direct condensing unit having a steam inlet port and the lower chamber of the reflux condensing unit having a water discharge port and a restricted passage for the escape of the water of condensation from the lower chamber of the direct condensing unit into the lower chamber of the reflux condensing unit, and a valve in said normally closed restricted passage for preventing the return of the water into the lower chamber of the direct condensing unit.

3. An air cooled steam condenser comprising a direct condensing unit having connected upper and lower chambers and a reflux condensing unit having connected upper and lower chambers, the reflux condensing unit bein located in proximity to the direct condensmgunit, the upper chamber of the direct condensing unit having a steam inlet port and the lower chamber of the reflux condensing a direct condensing unit having connected upper and lower chambers and a reflux condensing unit having connected upper and lower chambers, the reflux condensing unit being located in proximity to the-direct condensing unit, the upper chamber of the direct condensing unit; having a steam inlet port and the lower chamber of the reflux condensi'ng unit having a water discharge port and a restricted passage for the escape of the water of condensation 'fromthe lower chamber of the direct condensing unit into the lower chamber of the reflux condensingunit, a valve in said normally closed restricted passage for preventing the return ofthe water into the lower chamber of the direct condensing unit, a vent to external atmosphere from the upper chamber of the reflux condensing unit, and a water overflow passage for the lower chamber of the reflux condensing unit, the overflow end of which is at a higherlevel than said lower chamber of the reflux condensing unit and'the chamber end of such passage is normallywater sealed to'that the steam is caused to pass upwardly through the reflux condensing unit.

5. An air cooled steam condenser comprising a direct condensing unit having'connected upper and lower chambers and a reflux condensing unit having connected upper and lower chambers, the reflux condensing'unit being located in proximity to the direct condensing unit, the upper chamber of the direct condensing unit having a steam inlet port and the lower chamber of the reflux condensing unit having a water discharge port and a restricted passage for the escape of the water of condensation from the lower chamber of the direct condensing unit into the lower chamber of the reflux condensing unit,,a valve in said normally closed restricted passage for preventing the return of the water into the lower chamber of the direct condensing unit, a vent to external atmosphere from the upper chamber of the reflux condensing unit, a Water overflow passage for the lower chamber of the reflux condensing unit, the overflow end of which is at a higher level than said lower chamber of the reflux condensing unit andthe chamber end of such vpassage is normally water sealed so that the steam is caused to pass upwardly through the reflux condensing unit, and a water filling opening for the upper chamber of the reflux condensing unit.

In testimony that we claim the foregoing as our joint invention, We have signed our names this 30th daypf March 1926.
